MacX, I think you are making the a more complicated thing out of it than it really is. All the State of Texas is concerned about is getting their 6 1/4% sales tax. However, you need to get this done before you spend money on it because then it will appraise for more and you will have paid 8 1/4% sales tax on the parts. The vehicle you have pictured should easily be appraised at less than $1000. You do not need to take it to a licensed inspector if you do a title only transfer and and put 5 year antique plates on it once you get it running. Find someone with a dealers license and describe the vehicle as non running, no brakes, major parts present, but some parts missing, and bad paint and there will be no problem. A bond is required because there is some flaw in the transfer and there is a remote chance that someone will come forward and say the vehicle is theirs. If this should happen, the bonding company will satisfy this person up to 3 times the original appraisal. If after 3 years, there is no dispute, it becomes a regular blue Texas title. I still suggest you call these people.
